Add (back) a `tractor._testing` sub-pkg Since importing from our top level `conftest.py` is not scaleable or as "future forward thinking" in terms of: - LoC-wise (it's only one file), - prevents "external" (aka non-test) example scripts from importing content easily, - seemingly(?) can't be used via abs-import if using a `[tool.pytest.ini_options]` in a `pyproject.toml` vs. a `pytest.ini`, see: https://docs.pytest.org/en/8.0.x/reference/customize.html#pyproject-toml) => Go back to having an internal "testing" pkg like `trio` (kinda) does. Deats: - move generic top level helpers into pkg-mod including the new `expect_ctxc()` (which i needed in the advanced faults testing script. - move `@tractor_test` into `._testing.pytest` sub-mod. - adjust all the helper imports to be a `from tractor._testing import <..>` Rework `test_ipc_channel_break_during_stream()` and backing script: - make test(s) pull `debug_mode` from new fixture (which is now controlled manually from `--tpdb` flag) and drop the previous parametrized input. - update logic in ^ test for "which-side-fails" cases to better match recently updated/stricter cancel/failure semantics in terms of `ClosedResouruceError` vs. `EndOfChannel` expectations. - handle `ExceptionGroup`s with expected embedded errors in test. - better pendantics around whether to expect a user simulated KBI. - for `examples/advanced_faults/ipc_failure_during_stream.py` script: - generalize ipc breakage in new `break_ipc()` with support for diff internal `trio` methods and a #TODO for future disti frameworks - only make one sub-actor task break and the other just stream. - use new `._testing.expect_ctxc()` around ctx block. - add a bit of exception handling with `print()`s around ctxc (unused except if 'msg' break method is set) and eoc cases. - don't break parent side ipc in loop any more then once after first break, checked via flag var. - add a `pre_close: bool` flag to control whether `MsgStreama.aclose()` is called *before* any ipc breakage method. Still TODO: - drop `pytest.ini` and add the alt section to `pyproject.py`. -> currently can't get `--rootdir=` opt to work.. not showing in console header. -> ^ also breaks on 'tests' `enable_modules` imports in subactors during discovery tests?
